Fibrous damping baseball bat main body and fabrication method thereof

Abstract

The invention discloses a fibrous damping baseball bat main body and a fabrication method thereof. The baseball bat main body comprises a striking part, a connecting part and a grip part which are integrally and sequentially connected together, wherein, one end of the connecting part stretches into the striking part, an annular cavity is formed between an outside wall surface of the connecting part and an inside wall surface of the striking part, and a damping ring is arranged in the annular cavity. The fabrication method comprises the following steps: selecting and winding a fiber cloth to form the soft striking part, the connecting part and the grip part; and connecting the striking part, the connecting part, the grip part and the like for integration, placing the integrally connected parts in a die, and curing and molding to obtain the fibrous damping baseball bat main body. The fabrication method has the advantages that the ratio of defective products is extremely small, the conformity rate of the baseball bat main body is greatly improved, and the production cost is lowered; meanwhile the integrally molded fibrous baseball bat main body with a hollow structure has the advantages of light weight, good elasticity, excellent batting performance, high integral structure strength and less possibility of rupture or dent; and by utilizing the damping ring, the baseball bat main body has a good damping function.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a fibrous shock-absorbing baseball bat body and a manufacturing method thereof. Background technique [0002] With the vigorous development of sports, baseball, as a kind of sports, attracts many fans with its high skill and strong stimulation. In baseball, a baseball bat is a tool used by the user to swing a high-speed ball. Therefore, a better baseball bat must have the advantages of light weight, strong rigidity, good elasticity, and good shock absorption. It must also be able to withstand the huge impact force of the high-speed sphere in an instant. [0003] At present, the used baseball bats of baseball can be roughly divided into wooden baseball bats, metallic baseball bats and baseball bats containing fiber. [0004] Among them, the price of wooden baseball bat is the cheapest, so it is very popular. However, it has some disadvantages. At first, the overall weig...

Problems solved by technology

[0007] For example, in the prior art, a fiber-reinforced plastic baseball bat made by combining fiber material with plastic is specifically made by pre-impregnating the fiber bundle with molten thermoplastic, and then winding it in a predetermined direction on a ball with a ball. The outer shell is formed on a stick-shaped mandrel, and finally a baseball bat can be obtained by taking out the mandrel and modifying it appropriately. This kind of manufacturing method is called filament winding method, and the man-hour required for its manufacture is longer. , the production efficiency is low; and, during the winding process, the mandrel must be kept at an appropriate temperature so that the above impregnated thermoplastic will not solidify, but it is difficult to keep the temperature at each position of the whole mandrel consistent, therefore, some impregnation has The fiber bundles of thermoplastics are solidified before winding and cannot be bonded to adjacent layers of fiber bundles. In this case, the strength of the baseball bat will be reduced. In addition, the tension between the layers when the fiber bundles are wound Stacked together, therefore, the bonding between the layers is not tight enough, and the structural strength of this kind of baseball bat is not high enough;

[0008] Another example is another existing technology that uses thermoplastics as the base material and fiber material as the reinforcing material. The manufacturing method is to first take a high-temperature-resistant and elastic inner tube, and place it on the surface of the inner tube. Wrap a layer of thermoplastic base material, and then wind a long fiber reinforcement layer, and repeat this to form a tube with a laminated outer shell, which is placed in a mold and cured. Therefore, its strength must be It is better than the fiber-reinforced plastic baseball bat made by the above-mentioned winding method; however, in actual use, it will be found that its structural strength is still not high enough, and it cannot maximize shock absorption to meet the needs of users, and at the same time, the This production method is more complicated and prone to defective products in the production process
